For HP I thought it would be good to keep it for leveling up since if you selected your Life Pokemon early on you most likely would get the bare minimum of almost essential functions. As for the other stats I can just figure out the average height and weight of Pokemon from each reigon and apply that figure to that game. What I like about this is that you get to choose to either get a favorite team and face the potential challenges that come with it, ot try to get the best stats and work to find the best team for that.
